Rick Diamond/Getty Images for CMTOn Friday night, you'll be able to watch Katy Perry duetting with country star Kacey Musgraves on CMT Crossroads, the show that teams pop and rock performers with country acts. Right now, though, you can catch a sneak peek of the two award-winning ladies coming together for a duet on Katy's #1 hit "Roar."

In the preview clip, Katy sings "Roar" as usual, while Kacey joins her in harmony on the chorus. Then, Katy allows Kacey to sing the second verse by herself, joining her on the chorus the second time around. The two might even replicate that performance this summer when Kacey joins Katy as the opening act for part of her Prismatic world tour.

The full CMT Crossroads episode will feature Katy and Kacey singing together on more Katy hits like "Firework," and songs by Kacey like "Merry 'Go Round" and "Follow Your Arrow." The two also bust out a Dolly Parton cover. The fun gets underway Friday night at 10 p.m. ET on CMT.
